Elderly patients undergoing major surgery often develop cognitive dysfunction and the mechanism of this postoperative complication remains elusive. We sought to determine whether in old mice is associated with pathogenesis Alzheimer's disease.Prospective, randomized study.University teaching hospital-based research laboratory.One-hundred twenty C57BL/6 14-mo-old male (weighing 30-40 g).Mice received intraperitoneal injections either vehicle or Celastrol (a potent anti-inflammatory compound)...

Circular RNAs (circRNAs) have an important function in human diseases, especially cancer. circRNA hsa_circ_0014130 (circPIP5K1A), a particularly abundant circRNA, participates the tumorigenesis of non-small cell lung cancer (NSCLC), although underlying regulatory mechanism remains unclear. Here, we investigated circPIP5K1A role NSCLC. Expression NSCLC lines was explored with quantitative real-time PCR. The effect on evaluated silencing, miR-600 mimic transfection, and hypoxia-inducible...

Context Celastrol, acknowledged as a prominent exemplar of the potential for transforming traditional medicinal compounds into contemporary pharmaceuticals, has garnered considerable attention owing to its extensive pharmacological activities. The increasing volume publications concerning celastrol highlights importance in current scientific inquiry. Despite growing interest this compound, bibliometric analysis focused on subject remains be undertaken.

Abstract Background Because some of heat shock protein 90's (HSP90) clients are key cell cycle regulators, HSP90 inhibition can affect the cycle. Recently, celastrol is identified both as a novel inhibitor and potential anti-tumor agent. However, this agent's effects on rarely investigated. In study, we observed human monocytic leukemia line U937 Results Celastrol affected proliferation in dose-dependent way, arresting at G0/G1 with 400 nM doses triggering death above 1000 nM. Cell arrest...

Abstract Background Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide. Frequent tumor recurrence after surgery related to its poor prognosis. Although gene expression signatures have been associated with outcome, molecular basis of HCC not fully understood, and there no method predict using peripheral blood mononuclear cells (PBMCs), which can be easily obtained for prediction in clinical setting. Methods According microarray analysis results, we constructed a...

Abstract Cell adhesion molecules (CAM) expressed by vascular endothelium in response to cytokine stimulation play a key role leukocyte during the inflammatory response. Tripterine, chemical compound of Chinese plant Tripterygium wilfordii Hook f, displays anti-inflammatory properties several animal models. However, mechanisms its action are poorly understood. In present study, we show that conditions, mimicked tumor necrosis factor α (TNF-α) stimulation, pretreatment for 6 h with tripterine...

Elevated plasma statured fatty acids (FFAs) cause TLR4/MD2 activation-dependent inflammation and insulin tolerance, which account for the occurrence development of obesity. It has been confirmed that palmitic acid (PA) (the most abundant FFA) could bind MD2 to cellular inflammation. The natural compound celastrol improve obesity, is suggested via inhibiting inflammation, yet detailed mechanism still unclear. As reported directly target MD2, we thought disrupting binding between FFAs might be...

Abstract Introduction Glucocorticoid (GC) therapy is the main treatment for systemic lupus erythematosus (SLE). However, some patients are resistant to these agents. Abnormalities of glucocorticoid receptor (GR) seem be related steroid resistance. This study evaluated GRs in T lymphocytes and monocytes SLE by flow cytometry (FCM) using a monoclonal antibody (mAb) FITC-Dex probes. Methods Thirty-five with before 27 age- sex-matched normal controls were studied. Disease activity scores...

Celastrol is a novel anti-tumor agent. Ways to further enhance this effect of celastrol has attracted much research attention. Here, we report that treatment can elevate miR-223 in human breast cancer cell line MCF-7 and prostate PC3. Down-regulating could increase the number viable cells, yet it reduced cells samples were treated by celastrol; up-regulation displayed opposite effects. Celastrol's induction might be due NF-κB inhibition transient mTOR activation: these two events occurred...

The dysfunction of endothelial progenitor cells (EPCs) limits their potential for the treatment ischemia and atherosclerosis. Therefore, we investigated effect tripterine on EPC function examined underlying mechanisms. tripterine, an active component Tripterygium wilfordii Hook, enhancement efficiency transplantation was in vitro vivo. Treatment EPCs with at 2.5 µM 4 h inhibited oxidized low‐density lipoprotein (ox‐LDL) induced ROS production, cell apoptosis, senescence improved migration...

Celastrol, a novel HSP90 inhibitor, has recently attracted much attention due to its potential in multiple applications, such as anti-inflammation use, degenerative neuron disease relief, and tumor management. At present, the studies celastrol's effects on HSP90's clients have focused kinase sub-population, while another key nuclear transcription factors (TFs), is not being well-explored. In this study, we observe of celastrol 18 TFs (belonging clients) three human cell lines: MCF-7 (breast...

As a traditional Chinese medicine monomer derived from Tripterygium wilfordii Hook.f. with potential anticancer activity, celastrol can induce ferroptosis in hepatic stellate cells and inhibit their activation to alleviate liver fibrosis. Activation of effectively Hepatocellular carcinoma (HCC). Whether inhibits HCC by inducing remains be studied.

The development of resistance to therapy continues be a serious clinical problem in lung cancer management. Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is one the most common chemotherapy drugs treat non-small-cell cancer. However, almost all treatments fail after ∼1 year treatment because drug tolerance, probably occurring from threonine 790 mutation (T790M) EGFR, resulting overactivation EGFR. Celastrol natural compound that exhibits antiproliferative activity. In...

Hyperglycemia can exacerbate cerebral ischemia/reperfusion (I/R) injury, and the mechanism involves oxidative stress, apoptosis, autophagy mitochondrial function. Our previous research showed that selenium (Se) could alleviate this injury. The aim of study was to examine how alleviates hyperglycemia-mediated exacerbation I/R injury by regulating ferroptosis. Middle artery occlusion (MCAO) reperfusion models were established in rats under hyperglycemic conditions. An vitro model created with...

Immunological alterations have been reported to be involved in glioma, the most common malignant disease of adult brain. Our recent study identified higher levels IL-17 glioma specimens. The present investigated role and possible mechanisms tumorigenesis. Human cDNA was cloned inserted into eukaryotic pEGFP-N1 expression vector, which used transfect U87MG cell line, resulting a high level these cells. cells were then transfected with (pEGFP-N1-IL-17-U87MG) or mock (pEGFP-N1-U87MG) vector...
